What are the key features of MCP810T-315I/TT?
- Fixed 3.075 V reset threshold with ±2% accuracy providing reliable power-on and brownout detection for 3.3 V microcontroller systems
- Active-high push-pull reset output compatible with direct connection to active-high RESET pins without external pull-up resistors
- Internal 140 ms reset timeout delay ensuring supply voltage stabilizes fully before releasing the RESET line after power-on
- Tiny 3-pin SOT-23 package with low quiescent current enabling cost-effective voltage supervision with minimal BOM impact
What is MCP810T-315I/TT used for?
The MCP810T-315I/TT is used to supervise the 3.3 V supply rail of microcontrollers, FPGAs, and DSPs, asserting a reset signal during power-up, brownout, and power-down events to prevent processor lock-up or data corruption. Its active-high output and 3.075 V threshold make it a drop-in supervisor for systems using ARM Cortex-M or PIC microcontrollers with active-high reset requirements. The 3-pin SOT-23 footprint simplifies board layout and minimizes area consumption in handheld devices, industrial controllers, and communication modules.

Frequently Asked Questions
At what supply voltage does the MCP810T-315I/TT assert its reset output, and how accurate is that threshold?
The MCP810T-315I/TT asserts its active-high RESET output when the monitored supply falls below 3.075 V, with a threshold accuracy of ±2%, meaning the actual trip point is guaranteed between approximately 3.014 V and 3.136 V across temperature and supply variations.
How long does the MCP810T-315I/TT hold the reset signal after supply voltage recovers above the threshold?
After the supply voltage rises above the 3.075 V threshold, the MCP810T-315I/TT holds the RESET output asserted for an internal timeout delay of approximately 140 ms, allowing the power supply output to stabilize and the oscillator to start before the processor is released from reset.
Can the MCP810T-315I/TT be used to directly drive an active-high RESET pin on a 3.3 V ARM Cortex-M microcontroller?
Yes, the MCP810T-315I/TT features a push-pull active-high output that drives the RESET line to VCC during normal operation and to GND during a reset event, making it directly compatible with active-high RESET pins on 3.3 V ARM Cortex-M devices without requiring any pull-up resistors.
How does choosing MCP810T-315I/TT over a discrete RC reset circuit benefit system reliability in industrial environments?
A discrete RC reset circuit drifts with temperature and component tolerances, can fail to detect slow voltage droop, and provides no defined reset timeout, whereas the MCP810T-315I/TT guarantees a ±2% threshold at 3.075 V, a defined 140 ms delay, and brownout detection, reducing the risk of microcontroller lock-up across the -40°C to +125°C industrial temperature range.
